Abstract
Testing of chemicals that enter our waterways is necessary to keep marine environments healthy. The current method of toxicity testing is the larval growth and survival (LGS) test, which exposes larval fish to varying concentrations of a test chemical. This test uses a large number of vertebrate animals and has been shown to cause harm and distress to the larval fish used. Given recent legislation, it is important to find an alternative toxicity testing method. In this research, we have compared the results of the standard LGS test with the results from two alternative tests, the mysid test and the fish embryo toxicity (FET) test. The mysid test uses invertebrate animals, Americamysis bahia, to complete, and the FET test uses fish embryos. Using nickel as a test chemical as it is commonly found in waterways, both the mysid and FET tests showed promise in becoming an alternative testing method to the LGS test.
